復制代碼 代碼如下:

Users ModelUser = new Users() { ID = 10000, Name = UserName, UserName = UserName, PassWord = PassWord, Roles = "admin" };//用戶實體
string UserData = SerializeHelper.Instance.JsonSerialize<Users>(ModelUser);//序列化用戶實體
//保存身份信息，參數說明可以看提示
FormsAuthenticationTicket Ticket = new FormsAuthenticationTicket(1, UserName, DateTime.Now, DateTime.Now.AddHours(12), false, UserData);
HttpCookie Cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(Ticket));//加密身份信息，保存至Cookie
Response.Cookies.Add(Cookie);

復制代碼 代碼如下:

/// <summary>
/// 獲取用戶登錄信息
/// </summary>
/// <returns></returns>
public Users GetUser()
{
if (HttpContext.Current.Request.IsAuthenticated)//是否通過身份驗證
{
HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];//獲取cookie
FormsAuthenticationTicket Ticket = FormsAuthentication.Decrypt(authCookie.Value);//解密
return SerializeHelper.Instance.JsonDeserialize<Users>(Ticket.UserData);//反序列化
}
return null;
}

復制代碼 代碼如下:

/// <summary>
/// 權限驗證
/// </summary>
public class AuthAttribute : ActionFilterAttribute
{
/// <summary>
/// 角色名稱
/// </summary>
public string Code { get; set; }
/// <summary>
/// 驗證權限（action執行前會先執行這里）
/// </summary>
/// <param></param>
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
//如果存在身份信息
if (!HttpContext.Current.User.Identity.IsAuthenticated)
{
ContentResult Content = new ContentResult();
Content.Content = string.Format("<script type='text/javascript'>alert('請先登錄！');window.location.href='{0}';</script>", FormsAuthentication.LoginUrl);
filterContext.Result = Content;
}
else
{
string[] Role = CheckLogin.Instance.GetUser().Roles.Split(',');//獲取所有角色
if (!Role.Contains(Code))//驗證權限
{
//驗證不通過
ContentResult Content = new ContentResult();
Content.Content = "<script type='text/javascript'>alert('權限驗證不通過！');history.go(-1);</script>";
filterContext.Result = Content;
}
}
}
}

復制代碼 代碼如下:

public class HomeController : BaseController
{
[AuthAttribute(Code = "admin")]//驗證通過（這個action只允許admin查看）
public ActionResult Index()
{
Users ModelUser = CheckLogin.Instance.GetUser();
return View(ModelUser);
}
[AuthAttribute(Code = "user")]//驗證不通過
public ActionResult Index2()
{
return View();
}
[AuthAttribute(Code = "admin")]//驗證通過，發生異常
public ActionResult Index3()
{
return View();
}
}

復制代碼 代碼如下:

[ErrorAttribute]
public class BaseController : Controller
{
//所有Controller都繼承BaseController，則都會進行異常捕獲
}

復制代碼 代碼如下:

/// <summary>
/// 錯誤日志（Controller發生異常時會執行這里）
/// </summary>
public class ErrorAttribute : ActionFilterAttribute, IExceptionFilter
{
/// <summary>
/// 異常
/// </summary>
/// <param></param>
public void OnException(ExceptionContext filterContext)
{
//獲取異常信息，入庫保存
Exception Error = filterContext.Exception;
string Message = Error.Message;//錯誤信息
string Url = HttpContext.Current.Request.RawUrl;//錯誤發生地址
filterContext.ExceptionHandled = true;
filterContext.Result = new RedirectResult("/Error/Show/");//跳轉至錯誤提示頁面
}
}
